Actually, yes, the LO3 was an Iroc base option in 88, even 89. I don't think they were in 87, the LG4 was still around. Not popular, but it was a BASE option.

Also, a member known as iroc22 owned one.

Correct on all accounts. You could indeed get an LO3 in an IROC car. In '92 you could get a 305 TPI in an RS according to the origonal GM options list. However, not one single person ordered one because the cost was greater than just buying a Z28.

Little did those people know that if they actually did get the only 305 TPI in an RS, that car would be worth ALOT of money one day.
